Question to the Home Office:

To ask His Majesty's Government, with reference to the Animals in Science Regulation Unit Annual Report 2024, published in December 2025, what steps they are taking to prevent and sanction non-compliance to regulations including (1) the re-use of animals for testing without licence, (2) depriving animals used for testing of food and water and, (3) animals used for testing dying due to drowning or starvation.

The Government remains fully committed to continuous improvement in the regulation of the use of animals in science, and to strengthening the UK’s position as a global leader in science and innovation. As part of this, the Home Office is in the final stages of delivering a comprehensive programme of regulatory reform to further strengthen the Animals in Science Regulation Unit (ASRU), ensuring confidence in the regulatory system and maintaining robust compliance with the Animals (Scientific Procedures) Act 1986 (ASPA).

As part of the reform programme, the number of inspectors will increase from 14.5 full-time equivalent (FTE) positions at the end of 2017 to 22 FTE positions by March 2026.

All licensed establishments must fully uphold the standards for animal welfare set out in ASPA and in the Code of Practice for the Housing and Care of Animals Bred, Supplied or Used for Scientific Purposes. ASRU conducts regular audits to assure compliance and takes any instance of non-compliance extremely seriously.

ASRU’s published Compliance Policy (www.gov.uk/guidance/animal-testing-and-research-compliance-with-aspa) sets out how the regulator identifies, investigates and responds to potential incidents of non‑compliance, and how it applies appropriate and proportionate measures and sanctions where breaches are found. Through the delivery of this policy, the regulator aims to minimise the risk of future non‑compliance.

The Government’s strategy Replacing Animals in Science: A strategy to support the development, validation and uptake of alternative methods sets out a long-term vision to accelerate the development and use of nonanimal approaches. The Home Office will continue to apply ASPA’s rigorous licensing framework, ensuring that animals are only used where no validated non-animal alternative exists.
